So far, you only have 14 bars, but I will fix that soon. Click the squares to add/delete notes. Use the left and right arrow to increase/decrease the tempo, or use the plus and minus button. Press the play button to play the music. Click the instrument to change it. Click "Regular" to switch it to Loop, and click it again to switch it back.
